nbextensions tab is missing in Jupyter Notebook Server

[gentleanimal]

I am using Win 10 system with Anaconda installed. Jupyter Notebook version is 6.1.6 I first noticed I did not have type hinting after the last update. I also did not have nbextensions so I went to the GitHub page and followed the download instructions. At the Anaconda base prompt, I downloaded NBextensions and the configurator using conda install -c conda-forge jupyter_nbextensions_configurator. I tried it out and did not have the extensions tab or the hinting so came on this site and looked and found issues #129 and that also referred me to #125. I tried #125 first and changed the render.js file from notebook/js/mathjaxutils to base/js/mathjaxutils and that didn't give me the Nb tab so I then put the notebook/js/mathjaxutils back in the render file and then downgraded the Jupyter notebook to 6.1.5 and that did not work either. I still do not have hinting either. I would appreciate any help, please. I did run a debug on the Jupyter Notebook 6.1.6 and got two 304s, one on css file the other on a kernel. I don't know what they mean. Attached is the debug file.

Same issue. Older versions worked fine.

In my pursuit to find answers, this is a continuation of Issue #130. I decided to update my anaconda install to start over. This installed version 6.1.6 Jupyter Notebook. I then installed NBextensions using conda install -c conda-forge jupyter_nbextensions_configurator. I left the Anaconda prompt and restarted it, then I opened jupyter notebook with debug. Now I have my NBextensions tab but it looks like it is all disabled or not correct, check out my attached snippet png. Also my debug and jupyter nbextensions list, and jupyter paths. I can see I have problems but not sure of what to do next. HELP! LOL

Thank you all for your help!

hello, Basically, jupyter-notebook moved a .js file in a recent update causing the extensions tab to no longer appear.

Reverting to an older version works-around the issue:

pip install notebook==6.1.5

Thank you @jgaman,
I installed the jupyter notebook 6.1.5 but still no autocomplete so I downgraded jedi 0.18 to jedi 0.17.2 and now I at least I have the autocomplete. I will try later to download nbextensions and nbextensions configuator, of which I took out, because I have a project to complete. LOL Thank you so much, I hope when I do reinstall the extensions I won't have any problems.

Hi @jgaman ,
I installed nbextensions configuator in my anaconda base and got the same results as in my 2nd post with the screen shot the same and when I hovered over the highlighted extension, jupyter-js-widgets, it told me it was not compatible. Also, I attached a text file of the debug and jupyter NBextensions List. Please check it out and let me know what you think.
